Thyroid stimulating hormone (TSH) determinations before and after thyrotropin-releasing hormone (TRH) stimulation were obtained in 834 infertile women, from 1982 until 1985. Thyroid function disturbances were seen in 20% of the women, in accordance with the prevalence in South Germany. Postcoital tests were significantly poorer in women with subclinical hypothyroidism than in euthyroid patients. Spontaneous conception was more frequent in euthyroid (16%) than in hypothyroid (6%) women. During the same period, prolactin was determined after TRH stimulation in the early follicular phase and after metoclopramide stimulation in the luteal phase, in 759 women. The pregnancy rate was not improved by administration of dopamine agonists in women with an exaggerated response to TRH or metoclopramide. Our results suggest that subclinical hypothyroidism as well as disorders of prolactin secretion may play a role in infertility. The TRH test is proposed to rule out thyroid dysfunction. Neither the TRH nor the metoclopramide test was useful for the prognostic differentiation of prolactin secretion disorders.
UNLABELLED: In order to examine the effect of dehydroepiandrosterone-sulfate (DHA-S) on the production of uterus-contractive substances in perinatal women, the concentrations of estrogen stimulated neurophysin (ESN), oxytocin, 13, 14-dihydro-15-keto-Prostaglandin F2 alpha(PGF2 alpha) and DHA-S related steroids in the maternal blood of 12 cases of primigravida were serially estimated after intravenous administration of 200mg DHA-S twice a week from 38 weeks of gestation till the onset of labor. RESULTS: 1) The duration of labor was significantly shortened in the DHA-S group (mean; 9.3 +/- 2.8 hours) compared to the 11 control cases (13.5 +/- 5.2 hours). 2) i) The ESN concentration, which correlated well with that of free estradiol-17 beta, increased significantly at 1 week after the Ist administration. ii) The oxytocin concentration, which correlated well with that of ESN, increased significantly at 39 weeks of gestation, the first stage of labor and especially at delivery compared to the control. iii) The PGF2 alpha concentration, which increased in parallel with those of DHA-S, estrone-S and pregnenolone-S, increased significantly at delivery in comparison with the control and correlated well with estrone-S in the DHA-S group. CONCLUSION: These findings suggest that DHA-S administration to perinatal women may enhance the production of ESN, oxytocin and PGF2 alpha in the fetoplacento-maternal compartment, which may result in the shortening of labor.
